Our mosquito management program is affected by the changes in weather patterns from year to year.
Weather Patterns and Mosquito Management
Our program aligns with increased rainfall and warmer weather. Mosquito numbers fluctuate due to environmental factors, such as the predicted La Nina weather event. Dr. Cameron Webb (University of Sydney & NSW Health Pathology) explains that this weather pattern will significantly increase mosquito numbers in areas like Geelong and the Bellarine.
In the past five years, lower than usual rainfall has resulted in fewer mosquitoes. Recent lower rainfall and higher temperatures have also led to lower mosquito numbers than previous seasons. However, community members should still protect themselves as mosquito-borne diseases can be present even with low mosquito numbers.
Monitoring and Treatment
We monitor and treat large wetlands, known breeding areas. Our treatment must be done in the larval stage to prevent adult mosquitoes from emerging. Effective larvae treatment must occur within a few days during certain stages of development. Once mosquitoes have emerged, nothing can be done.
Residents can help by:
- Maintaining pools, spas, and fishponds.
- Removing water from blocked gutters, old pots, toys, bird baths, or stagnant ponds.
- Covering openings to rainwater tanks with mesh.
Protect Yourself
Community members are encouraged to protect themselves and their families from mosquito bites by:
- Wearing light-coloured, loose-fitting clothing.
- Covering arms, legs, and feet.
- Using an effective insect repellent.
